Cruise Control - optional fitment on 1.6 ltr Elise; not available on other models.
Caution: Cruise control should be used only when conditions are favourable; on straight, dry, open roads with
light traffic.
The cruise control system is incorporated into the engine ECU programme, and allows the maintenance
of a selected vehicle speed above 30 mph (50 km/h), without having to use the accelerator pedal. The tell tale
lamp in the gear lever shroud is lit whenever cruise control is active.
Operating cruise control
Two switch buttons are provided on the
end of the left hand steering column stalk;
an upper rocker switch to set the speed, and
a lower push button to switch off the cruise
control.
Setting the vehicle speed
To engage cruise control, the vehicle
must be travelling at 30 mph (50 km/h) or
more. Accelerate to the desired cruising speed
and then press once the 'I' end of the rocker
switch with the raised pip. Cruise control will
engage and the set speed maintained when
the accelerator is released (road gradient and
winds permitting). The accelerator may be
used to increase speed temporarily without
affecting the setting.
Cruise control automatically disengages when; the foot or parking brakes are applied, a gearchange is
made, or when the vehicle's speed falls below 30 mph (50 km/h). To disengage it manually, press once the
'O' button.
Resuming a set speed
Caution: The resume function should be used only if the driver is aware of, and wants to return to, the set
speed.
To resume cruising after braking, changing gear or slowing below 30 mph (50 km/h), press once the 'R'
switch.
Changing the set speed
When cruise control is operating, press and hold the 'I' end of the rocker switch to accelerate the car.
Release the switch when the desired new speed is attained. Alternatively, repeated brief presses of the switch
will increase the setting by 1 mph (1.5 km/h) increments. Pressing the 'R', dimpled end of the switch will reduce
the set speed in like manner.
Otherwise, the car may manually be accelerated or braked to the desired new speed, and the 'I' switch
pressed once to set cruise at that speed.
Set speed cancellation
The set speed will be reset to zero when:
- The vehicle is stopped or;
- The parking brake is applied or;
- Reverse gear is selected or;
- The ignition is turned off.
Programming
Programming for the cruise control is incorporated into the 1ZR engine ECU programme.
